column - The column

value - The value

toString

public String toString()

Overrides:

toString in class Object

getRow2F

public <V extends VectorWritable2FType> void getRow2F(int row,
                                                      V out)

Description copied from interface: MatrixReadable2x2FType

Retrieve row row, saving the result to out.

Specified by:

getRow2F in interface MatrixReadable2x2FType

Type Parameters:

V - The precise type of writable vector.

Parameters:

row - The index of the row, starting at 0.

out - The output vector.

getRow2FUnsafe

public <V extends VectorWritable2FType> void getRow2FUnsafe(int row,
